Chiropractic works because you are an organism capable of self-healing controlled and directed by your nervous system. Millions of instructions flow from your brain, down the spinal cord, and to every organ and tissue. The signals returning to the brain confirm whether your body is functioning properly. Improper movement or position of the movable bones of the spine can interfere with this vital exchange by irritating nearby nerves and the tissues they control. Precise chiropractic adjustments are meant to improve mind-body communications. Health often returns with better control of the body by the nervous system.
